Mexican art historians weigh in on upcoming Kahlo's auction that could fetch up to $60 million

MEXICO CITY (AP) — Frida Kahlo’s “El sueño (La cama)” — in English, “The Dream (The Bed)” — is causing a stir among art historians as its estimated $40 million to $60 million price tag would make it the most expensive work by any female or Latin American artist when it goes to auction later this month.

Sotheby’s auction house will put the painting up for sale on Nov. 20 in New York after exhibiting it in London, Abu Dhabi, Hong Kong and Paris.
